There is another challenging portion of this subject matter that needs to be mentioned:

Forecasts suggest that when the world's population soars beyond 8bn in 20 years time, the global demand for food and energy will jump by 50%, with the need for fresh water rising by 30%.

But developing countries are already using significant proportions of their water to grow food and produce goods for consumption in the West, the report says.

"The burgeoning demand from developed countries is putting severe pressure on areas that are already short of water," said Professor Peter Guthrie, head of the Centre for Sustainable Development at Cambridge University, who chaired the steering group.

(BBC News). All this talk about global warming raising the depth of the ocean yet there being less and less drinking water, makes one think of the "water water everywhere, nor any drop to drink" saying of old.

The bottom line we have been told about year after year, decade after decade, which we have ignored up until now, is that the global ecosystem is one united and interwoven living realm, so when we do anything to it that is harmful, it propagates through the entire system.

The point to remember now, since we are so far into the sequence of damaging events, is that at some point in time there is a convergence into a perfect storm:

Song writers mentioned that "time keeps on slipping slipping slipping into the future" in a popular song some time back, while the exclamation "just in time" indicates that only a portion of the vast amount of the totality of time is available for some efforts.

Time is another one of those invisible realms, like gravity, that governs the earth from "the shadows", that is, the realm we cannot see even though we can see the effects of the unseen power at work....

[John Beddington, the UK government's chief scientific adviser] foresees each problem combining to create a "perfect storm" in which the whole is bigger, and more serious, than the sum of its parts.
